I'm about to give up but maybe its something simple...

I have been trying to install Leo4allV3 10.5.2 on my PC for months but have given up on it as I think its just too old and not supported. But now I am trying to get it to work on my brothers laptop.

Samsung R610
Core 2 Duo T5800 2.0ghz
NVIDIA 9200m 512mb DDR2
4gb DDR2 Kingston HyperX 800mhz http://www.newegg.com/Product/Product.aspx?Item=N82E168… ↗

I really just don't see why it wouldn't work. First I was getting the "Still waiting for root device" error. Then I reinstalled and played w/ the drivers a little. Now every time it starts to boot to where it would get that error it restarts.

I already screwed up his Windows 7 install so he lost everything and I'd at least like to get this working for him.

And if theres any chance of it working on my computer at all I have a:
Asus P4P800 SE motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E168… ↗
P4 2.8ghz, 800mhz FSB, 1mb L2 cache, Prescott core (not sure if this one is w/ HT or w/o)
1.5GB Ultra PC3200 RAM
Genuine ATI 9600 SE 128mb video card

I am getting the still waiting for root device error on this one too. I haven't played with the drivers list though as I really just learned of that today.
